Definitions

  • the invention relates to a battery heater for heating a vehicle battery, such. B. a lead-acid battery, the z. B. is used as a starter battery.
  • a battery heater is used with a super-coolable latent heat storage mass, which gives off heat after activation.
  • the latent heat storage material is located in a flat plastic bag, hereafter referred to as heat pad, and this heat pad contacts the battery bottom or a side wall of the battery. Furthermore, the heat pad is located on a heat-insulating plate, which prevents the heat generated flows in undesirable directions, d. H. other materials or components are heated.
  • the battery heating device has a movement device with which the heat pad can be selectively brought into contact with the battery, ie in thermal contact with the battery.
  • the heat pad When the battery is to be heated, the heat pad is in touching contact with the battery bottom or a side wall of the battery.
  • the heat-generating process is triggered by means known to the person skilled in the art, such as e.g. B. mechanical or thermal. After the dissipation of the heat of crystallization generated in the latent heat storage mass in the cold battery, this is heated by and then has a much better energy delivery capability, ie the vehicle can be restarted safely. Even a short time after starting the battery is heated even further.
  • the battery can be completely recharged within 30 to 60 minutes, which is not possible with a cold battery, for reasons known to a person skilled in the art.
  • the discharged energy In order to reactivate the latent heat storage mass, the discharged energy must be returned. This is done with an electrical resistance heating, which is powered by the alternator and / or the battery. The required temperature depends on the chemical composition of the latent heat storage material. Thereafter, the crystalline mass again assumes the liquid state.
  • the invention allows a separation of the heat pad from the battery, in which the plate on which the heat pad is arranged, a few millimeters from the battery is removed, so that creates an air gap between the heat pad and the battery wall or the battery bottom. Characterized heat conduction is prevented in the recrystallization in the battery, so that now the latent heat storage mass can be heated alone.

  • the recrystallized heat pad can be kept separate from the battery until battery heating is to be performed again. However, the heat pad can also be re-applied to the battery wall or battery bottom immediately after recrystallization.
  • the moving device is actuated by means of bimetallic elements 9.
  • the movable plate, on which the heat pad is arranged is coupled to bimetallic strip 9 via a coupling piece 10.
  • the heating current flows for the Recrystallization over the bimetallic strip 9, so that they bend by their own resistance heating, as shown in Fig. 2b.
  • the plate with the heat pad is separated from the battery, so that an air gap is created between the battery and the heat pad.
  • the heating voltage is turned off, so that the bimetallic strip 9 again assume their original state as shown in FIG. 2a and thereby the recrystallized heat pad again touches the battery.
  • the latent heat storage mass is arranged in a thermally insulated housing, wherein the contact surface to the battery case is not isolated. This ensures that the energy losses are reduced during the removal and the supply of heat energy.

  • Under the heat pad an electric heating foil 7 is arranged with a connecting cable 8.
  • the heat pad 5 is activated, so that the stored heat energy by crystallization of sodium acetate Trihydrate is free, ie the heat pad 5 is warm. Since the heat pad 5 touches the entire surface of the bottom of the battery 1, the battery 1 is also heated.
  • Figs. 2a and b show a second embodiment of the invention.
  • the container 4 is moved by means of a bimetallic strip 9 in the direction of the arrow.
